seriously, nowadays the customer service is worst no matter main telcos or MVNOs.
consumers like us can only expect no issue and it will continue to last like that.
so far, the main issue is port-in, if port-in no issue, once ported so far can just use no issue actually. normal days do not really need to contact the CS at all.
i have used circle life, myrepublic mobile, zym, vivifi and eight now, so far never need to contact CS before except port-in issues which it happened quite often which need to contact CS to sort it out.
anyway, my eight account still has $520 to spend. so no chance to port out so unlikely will meet issue that need to contact CS also.
